AnyPCBA PCB and PCBA case studies
Traditional pet washing equipment relies on manual operation, making it difficult to achieve unmanned, self-service operation. This project required an intelligent control board for a pet self-service washing and drying machine, replacing manual control with automated, smart functionality.
Key Hardware Requirements:
Reliable Motor Control: Driving water pumps, circulation fans, and high-power heating elements for drying
Multi-Sensor Integration: Temperature, humidity, water level, flow rate, and door status monitoring
Remote Connectivity: 4G and WiFi communication for cloud management and mobile payment
Rugged Design: Operation in high-humidity, dusty environments with vibration resistance
We designed a highly integrated smart control board as the core control unit for the pet self-service washing machine.
Key design features:
Main Control Platform
Industrial-grade ARM Cortex-M MCU with extensive I/O and processing capability
Real-time processing of multiple sensor inputs and control logic
Communication Module
Onboard 2.4G WiFi and 4G CAT.1 cellular modules
Bidirectional data exchange with cloud servers
Supports remote monitoring, OTA firmware updates, and remote diagnostics
Motor & Load Drive
Multiple high-reliability MOSFET driver circuits
Precise control of washing pumps, circulation fans, and high-power dryers
Over-current, over-temperature, and stall protection
Sensor Integration
High-precision analog front-end for water temperature, air temperature/humidity, water level, flow rate, and door status
Real-time data acquisition for control decisions
Payment & Control Interface
Integrated 4G module with QR code payment interface
